Yup, I’m one of them.
My aunt traced our lineage back to 1374 in England. Then I later learned that one of our ancestors-—Thomas Dudley-— a governor of Massachusetts Bay Colony-— is descended from the English King Henry II of the Plantagenet Dynasty. Henry II, in turn is descended from Charlemagne, so that puts me into the Charlemagne club too, presuming all of this research is accurate.
Tom Dudley? That puritan catholic bastard? He got kicked out of England, and paid off with Massachusetts bay colony. Later founded Harvard. Married his daughter, Anne, off to William Bradstreet, who became the next Governor-General of Mass. Bay Colony. Anne Bradstreet wrote some trash poetry the you probably had to read in college.
Never heard of them, cousin.
